I changed the fingerprint, (apparently it's still 03:D6:42:23:03:D1:0C:06:73:F7:E2:BD:29:47:13:C3:22:71:37:1B according to www.grc.com/fingerprints.htm). I'm still getting the same error: ("Connection to firebase failed. Reconnecting to Firebase..."). Any idea where it could be going wrong? I would really appreciate some help here!

[@TrickSumo]

Hi Cayami, Just uploaded sketch to NodeMCU (with same SSL fingerprint) and its working as expected. 1. Possible solution:- Make sure Firebase URL in sketch is without '' and '/' at the end. 2. If issue still not resolved, try alternative library:- kzbin.info/www/bejne/pH3ddGNji8aketU Regards

As i saw the deadline of fingerprint was 6 of May and grc still shows the same code. Before 6 of May my code was connecting to firebase but now it does not. What should we do now? How can i get new fingerprint?

[@TrickSumo]

Hi Sedat Turunç , To manually check fingerprint, follow below steps:- 1. Go to realtime database >> rules and set rules as :- ------------------------- { "rules": { ".read": true, ".write": true } } --------------------------- 2. Now open browser windows and paste URL of database with ".json" at the end. Ex. ooooooo-a752c.firebaseio.com/.json 3. Manually check fingerprint as shown in the above video @ 1:40

[@TrickSumo]

As of 8 May 2020, certificate is valid from 21/02/2020 to 19/02/2021 Fingerprint is 03d6422303d10c0673f7e2bd294713c32271371b

Maybe NodeMCU got damaged.

thanku! i checked my code almost 100 times ! i was suprised as i have done this before with the same code and now i know the reason. but why do they change their fingerprint?

[@TrickSumo]

Hi, SSL certificates are issued for a period of time (like 3 months or 1 year). When the certificate renews, fingerprint also changes. To get rid of this issue, you can use an alternative library:- kzbin.info/www/bejne/pH3ddGNji8aketU&lc=UgzZsgxMbFPDcj5msuN4AaABAg
